We thought we'd have to wait months for this, but Kim and Kanye's newborn daughter Chicago West made her debut in the video Kylie Jenner posted to commemorate the birth of her own baby girl yesterday, and she's a cutie! The little one looks a lot like Kimye's two other kids North and Saint, but we couldn't get the best look because the glimpses of her were so brief.

We thought that Kim would definitely wait and do a Beyonce-esque massive reveal on Instagram, but apparently she was cool with taking the back seat to her little sister's big announcement.

Speaking of which, we can't believe Kylie shared all of this, after nine months of secrecy. She explained to her fans that she wanted to keep things private to have the most positive experience, but now that the baby is here she's sharing all her happiness with the world.
